Caras Galadhon (pronounced [ˈkaras ˈɡalaðon]) was the chief city of Lórien.

Caras Galadhon was in the Naith of Lórien, in the heart of the Silvan Elves' realm. It was built in the middle of, on top of, and out of the mallorn trees that Galadriel had brought with her from Valinor. At its heart was the residence of Celeborn and Galadriel.

In the Fourth Age, after Galadriel had gone into the West, Caras Galadhon was ruled by a lonely Celeborn as capital of a Lórien which now spanned both sides of the river Anduin. Later Celeborn left for Valinor as well, and Caras Galadhon became an empty place.
